We welcome contribution in any area, if you don’t have developer skills, you
can always contribute to Localization or just donate us money. In case you are
interested in fixing some code, please read Gammu internals to
understand structure of Gammu code. We also maintain list of
wanted skills where you can find in
which areas we currently mostly lack manpower.

As we use Git for development, the preferred way to
get patches is in form which can be directly applied to Git. So start with
cloning our Git repository:

gitclonehttps://github.com/gammu/gammu.gitgammu

Once you have done that, do some fixes and commit them (see
Git tutorial
for information how to work with Git). Once you’re satisfied with your
results, you can send the patches (all changes you’ve made so far) to us:

gitsend-email--to=gammu-users@lists.sourceforge.netorigin

Please note that mailing list
requires you to subscribe before posting. This is anyway good idea in case you
want to contribute. However if you don’t want to do that, just send the mails
directly to one of authors:

If for whatever reason you don’t want to use Git, you can also manually create
patches using diff. Also we can handle if you send us just the file
you have changed with reference where did you take it.

To manually create patch you can use following steps:

Copy source with Gammu, you start from, into gammu directory.

Copy source with Gammu, you want to modify, into work directory.

Make your changes in work directory.

Go into parent directory, where gammu and work directories are
placed.
